METHOD OF MAKING SHOES.

making shoes and in particular to improve-- ments in processes of making shoes which involve molding the shoe upper.

An important object of the present invention is to produce a shoe which is both light and durable and which can be manufactured with a minimum of labor and expense.

More particularly the invention aims to reduce the number of steps performed in making a shoe of the type hereinshown and at the same time to reduce the amount of material required to produce said shoe without affecting the quality of the shoe.

Other objects and features of the invention will appear from the following descrip tion and claims when considered in connection with the accompanying drawings in which,

Figure 1 is a perspective view of a shoe embodying this invention, the heel end of the shoe being shown partly in section; and

Fig. 2 is a perspective view of a sole used in making the preferred form of the shoe of this invention.

In carrying out the process of this invention in one manner in which it has been successfully practised, the heel end of the shoe upper 3 is first molded, preferably by a machine of the type shown and described in the specification of application for British Letters Patent No. 10,360 of 1914, to provide an inturned flange 5 extending about the heel end of the upper. The heel portion of the sole 6 is then split or gouged out so as to form a flap or tongue 8, the full thickness'of the sole being retained around 'the marginal edge of the sole to provide a randshoulder 9. The upper with the counter and'lining is then assembled upon a last and pulled over in the usual manner, the in-'- turned flange 5 of the upper being positioned between the flap or tongue 8 and the heel end of the sole 6. The forepart of the shoe is then lasted in the usual manner and Specification of Letters Patent.

" the outturned flange 12 of the upper about the forepart of the shoe secured to the sole by stitches 15. At this stage in the process the heel end of the shoe, including the flap 8, the marginal edge of heel portion of the sole bled on the last in the relative positions they are to occupy in the finished shoe, that s, with the inturned flange 5 of the upper lnterposed between the flap 8 and the heel end of the sole. In the next step ofthis are loosely assemthe upper'and the process, the several parts of the shoe at the heel, together with a heel 16 if a heeled shoe is to be produced, are secured together in a single operation by fastenings 18 which are positioned so as to pass through the heel, sole, and inturned flange of the upper and Ere clenched upon the upper'surface of the It will be noted that the shoe produced by. this process has only a single set of fastenings in the heel end thus effecting a saving of labor and material over the present practice of lasting the heel portion of the upper on to a heel seat independently of the heel seat nailing and heel. attaching operations and also providing a more comfortable and satisfactory heel seat for the shoe. It will be further noted that the flap or tongue 8 is formed in the heel end of the sole in such a manner that the marginal edge 9 of the sole at the heel provides a shoulder to support the rounded lower edge of the counter and prevent it from running over. The extra thickness about the marginal edge of the heel end of the sole also acts as a rand to compensate for the curvature of the bottom face of the heel of the last, thereby providing a flat heel seat upon which to nail the heel or if a spring heel shoe is to be produced, the formation of the sole at the heel enables the offset heel porupper and the sole in such manner tion of the sole to the inturned flangeof the flap in a single operation. 2. That improvement in the art of making shoes which consists in molding the heel end flange extending between the flap and' the heel end of the sole, securing the upper to the sole about the forepart, and securing together the heel portion of the sole, thelinturned flange of the upper and the flap in one operation.

3. That improvement in the art of making shoes which consists in splitting the heel end of a sole, moldingthe heel end of gn upper to provide an inturned flange,

assembling the upper and sole upon a last with the inturned flange of the upper positioned between the split portions of the heel end of the sole, securing the upper to the sole about the fore art, and securing together the split portions of the sole and-the flange of the upper simultaneously.

- 4. That improvement in the art of making shoes which consists in molding the heel end of an upper-to rovide an inturned flange, splitting the bee end of the sole to form a flap, assemblingthe upper and sole upon a 1 st with the inturned "flange of the upper @Qfiflxtmned between the flap and the heel end 0 thesole and a heel to the inturned flange of the upper and the flap in asingle operation.

In testimony whereof I have signed my name to this specification.
